A single field error
The summary link focuses the matching field. Keep the same error below the field with aria-describedby; the static summary does not announce or move focus automatically.
import { FormErrorSummary, Input } from "@gunkin/uiify";
export default function Example() {
return (
<form className="example-form" aria-label="Project details">
<FormErrorSummary aria-label="Project errors" title="There is a problem" errors={[{ href: "#form-error-summary-single-project", message: "Choose a project name" }]} />
<div className="example-field">
<label htmlFor="form-error-summary-single-project">Project name</label>
<Input id="form-error-summary-single-project" name="project" invalid autoComplete="off" aria-describedby="form-error-summary-single-project-error" />
<p className="example-error" id="form-error-summary-single-project-error">Choose a project name</p>
</div>
</form>
);

Static section containing a heading and links to the supplied error targets. Every href must point to a real field id. This summary adds no alert role, live region, focus movement, or validation logic; fields retain their labels and inline aria-describedby relationships. Empty errors render nothing.
